under the heading, "learn something new everyday", I came across a way to carry and draw that works well, for me. I'm sort of the typical, old, fat, American guy. I watch youtube videos and see Hickok45 and others carrying IWB at 4 o'clock, I tried that and it sucks, starts messing with my back, useless in a car, probably prints. so for some time I was carrying OWB at 3o'clock with a big shirt, that sucked too. kind of by accident, I discovered 1o'clock or "Mexican carry"(Yankee Marshal explains that's a valid term). I had a Remora holster and started carrying that way. now have a IWB holster with clip and bought another Remora. here's what's going on--- the gut pushes the shirt out and gives plenty of tent effect down and over the belt line, any small gun (CM9) in a holster will be hidden in the waistband under the gut (hell, I could carry a 1911 there). plenty of padding there so it's very comfortable. with the gun right in front it's an easy matter to get the shirt up and lift the gun out, get 2 hands on it, lock the elbows into the sides and bang. very fast first shot. only holster setup I've ever tried that works; standing, sitting or driving.
(the down side to "appendix carry" is the first few hours when your worrying about shooting "Mr. Happy". get over that.)
